How do JavaScript redirects affect SEO?
For permanent URL changes, HTTP redirects are generally preferable because the redirect is communicated directly at the protocol level.
For example:
HTTP/1.1 301 Moved Permanently
Location: https://example.com/new-page
JavaScript navigation adds another processing dependency.
During migrations, validate:
- old URL;
- HTTP status;
- final destination;
- redirect chain;
- canonical;
- internal links;
- sitemap references.
Google's site-move documentation provides specific guidance for redirects and URL migrations.
